What Is DMD Chip?

DMD is a abbreviation of Digital Micromirror Device which is one of the most important part that reflects the light to the projector screen.

As we all know, a picture on the screen is composed of millions of pixels.

Every micromirror inside the chip stands for a pixel on the image.

When you see the bright area of the image, the DMD chip is reflecting the light from the bulb to the screen.

In another hand, the dark area is because of the light is reflected to the heatsink.

How many mirrors does a DLP chip have?

It depends on the native resolution of your DLP projector.

For example,

If your projector resolution is 1920*1080, there are 1920×1080=2,073,600 pieces micro-mirrors inside the chip.

Generally, the more micro-mirrors inside, the clearer image you will see.

When some of the micro-mirrors are broken, the light can not be reflected to elsewhere.

And those pixels are always bright when it need dark.

That is why you will find the white dots is display on the screen.

The numbers of white spots will be increasing very fast. So that you are not able to see any detail within a week if you do not replace the old chip.
